1) Interface
PROTOCOL RS-232C
BAUD RATE 9600 [bps]
DATA LENGTH 8 [bits]
PARITY BIT NONE

3) Control sequence
(1) Send the command from the personal computer to the projector. (The commands shall be sent at intervals
of at least 400ms.)
(2) The projector will send a return command 400ms* after it receives an end code. If the command is not
received correctly, the projector will not send the return command.
(3) The personal computer checks the command and confirms if the sent command has been executed or not.
(4) This projector sends various codes other than the return code. When having a control sequence by RS-
232C, reject other codes from the personal computer.
* : The sending time of return command may delay depending on the (operating conditions) during changing
the input signal, etc.
